You can spend a fraction of that and get a killer track car. However, if you are hell bent on spending tons of money for a track car get the GT3 RS. Fairly low in upkeep...

Unfortunately you cannot order GT3 or GT3 RS any more. There are some on dealers lot, and you can buy a second hand one. You will not be able to get a GT3 RS 4.0. I tried and all the US allocation is gone. With big markup you may find one but you cannot change any specs.
